This is a vintage sterling silver whale pendant charm that measures 2" in length by 1" wide and has tested as 925 silver. It is beautifully made with a high polish finish which makes it look dark in my pictures only as it is bright in person. You will be pleased I"m sure. I also have a leather slider that can be used if you do not have a silver chain to slip this onto. The leather necklace measures 20" in length and I can put the pendant on it for you if you like. Just let me know at check out.
